NEW YORK, Aug. 15, 2013 /PRNewswire/ -- Fixed mortgage rates were little changed, with the benchmark 30-year fixed mortgage rate inching up to 4.57 percent, according to Bankrate.com's weekly national survey.

Adjustable rate mortgages were up more forcefully, with the popular 5-year adjustable rate jumping to 3.61 percent and the 7-year ARM to 3.98 percent. Mortgage rates have been range bound since late June, but where they move within that range is dependent on what the market thinks about when the Federal Reserve will begin tapering their bond purchases. Talk of a September tapering has kept mortgage rates in the upper half of that range in the past couple weeks. As recently as May 1st, the average 30-year fixed mortgage rate was 3.52 percent. At that time, a $200,000 loan would have carried a monthly payment of $900.32. With the average rate currently at 4.57 percent, the monthly payment for the same size loan would be $1,021.71, a difference of $121 per month for anyone that waited too long.
